Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166984, here are decompositions:

5 + 166979 = 166984
11 + 166973 = 166984
17 + 166967 = 166984
53 + 166931 = 166984
113 + 166871 = 166984
131 + 166853 = 166984
137 + 166847 = 166984
281 + 166703 = 166984

Showing the first eight; more decompositions exist.
